This invention relates to tubular receptacles and a rocess for makingthe same. More particular y, this invention 1s directed to themanufacture and provision of a container such as tubes formed from athin, substantial- 1y water-proof non-metallic, flexible material.

To make clear some of the dominant features of the invention, it may benoted that where tubes are made by dipping or similar process like thathereinafter described, it is desirable to provide means for reinforcingthe tubular body at the mouth thereof and to furnish a substantial neckor mouth portion to receive a closure member or to co-operate with anattaching member on a container to form a closure therefor.

One object, therefore, of the invention, contemplates incorporating,with the shaped tubular body, a ring member preferably metallic and makean integral part of the tube during the process of manufacture, saidring serving to provide a substantial neck or mouth for the containerand at the same time giving the same a neat and finished appearance.

A further object is to provide a container of the character describedwhich shall be exceedingly light and yet tough, practically unbreakableand impervious to water.

A still further object of the invention is to provide an article of thecharacter described and a process for making the same, said articlebeing adapted to form a closure for bottles or similar'retainers and toserve as a graduate for measuring a predetermined quantity of liquid orfluid substance.

Another object of the invention is to provide an article of thecharacter described which is comparatively simple and easy to make,inexpensive to manufacture, neat in appearance and practical andeflicient to a high degree.

Other objects of this invention will in part be obvious and in parthereinafter pointed out.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter described and of which thesec e of application will be indicated in the fol owing claims.

In the accompanying drawing, in which is shown one of the variouspossible illustrative embodiments of this invention,

Referring in detail to the drawing, 10 represents a container embodyingthis invention. The body portion 10 of the container is preferablycomposed largely of nitro-cellulose compounded with or without rubber,but preferably with a small percenta e of rubber dissolved therein andmay be ma e up of one layer intimately united to form a coherent sheet.The composition used to form said body portion 10*, may be like thatdisclosed in the patent to Charles Weber, No. 1,350,533, issued August24th, 1920, or any other suitable material or compound which when dryforms a non-porous, non-absorbent, water-proof and flexible film sheet.

The process of making the article will now be described. A solution 11of nitro-cellulose or an equivalent substance prepared according to theusual and known methods is laced in a tank or vessel 12. A form memer orrod 13 is provided having an annular ring or band 14 snugly fittedthereon and spaced from the effective end thereof a distancesubstantially equal to the length of the desired article. This form isdipped into the solution 11 until a substantial portion of the ring 14is submerged, as is clearly shown in Fig. 1. The form member 13 is thenwithdrawn to permit the surplus solution to drip back into the vesseland the adhering film sheet on the member 13 is allowed to harden anddry, which it readily does when exposed to the air. For all generalpurposes, a single dipping has been found sufiicient to form a suitableand substantial container, but for special requirements, the form-member13 with the hardened coating thereon may be repeatedly dipped into thesolution 11 or into other equivalent solutions to increase the thicknessof the body portion 10.

The formed container 10 after drying on member 13 is removed therefromby subjecting it to heat, as for example applying steam or preferably byimmersing same in hot water, thus causing the body portion 10 and ring14 to expand and loosen from said m'em- The removal of the containerfrom the form may be greatly facilitated by making the member 13 of aglass or like material which has a relatively low co-efiicient ofexpansion as compared with the material forming the body portion 10".The band 14 may be formed of any suitable material but preferably ofsheet metal such as aluminum or the like which readily slips off themember 13 with the portion 10 when heated since its expansion isrelatively greater than that of the member 13.

I have found it preferable to employ sheet metal for the band 14 sincethe latter then forms a strong adhesive band with the material of thebody portion 10. Furthermore, the co-eflicient of expansion of thematerial of the body portion being greater than that of the metal band,the material shrinks about the former and embraces the same tightly,

thus forming a positive union of the band and body portion.

The interior wall of the band 14 may serve as a seat for a cap 15 asshown in Fig. 2 or as an attachment means for a bottle as shown in Fig.6.

In carrying out the above described process, it is to be understood thata large number of containers may be formed simultaneously, Fig. 1illustrating a fragmentary portion of an apparatus for carrying out theprocess, of which the form-member 13, it will be understood, may be onlyone of a group of spaced similar members. Tubular containers of sizesand shapes other than is shown in the drawing may be formed by providingform ornamental coloring effects may be produced in the container 10.

In Figs. 3, 4 and 5 are shown respectively modified forms 16, 17', and18 of the band or ring. The band 16 has its inner rim edge 16* outturnedto form a ridge for reinforcing the connection of the body portion 10 tothe band 16. The band 17 is provided with ribs 17, and band 18 with ribs18 and an outturned inner rim edge 18" for the same purposes.

Fig. 7 shows a sectional view of an adaptation of the invention forminga closure graduate 19. The band 20 thereof may be like any of thosedescribed above, or may be formed with a thread 20 which in Fig. 8 isshown fitted on a bottle 21 having a correspondingly threaded nec A linemark 22 for measuring a definite quantity of fluid, as for example, oneteaspoon may be engraved or otherwise formed on the body portion 10.

Containers made in accordance with this invention are particularlyadapted for holding medicinal preparations such as pills, tablets,fluids, and the like, which it is desirable usually to carry about theperson. The container may also serve for shipping samples of materialand for like purposes.

It will thus be seen that there is provided a device in which theseveral objects of this invention are achieved and which is well adaptedto meet the conditions of practical use.

As various possible embodiments might be made of the above invention andas various changes might be made in the embodiment above set forth, itis to be understood that all matter herein set forth or shown in theaccompanying drawings is to be interpreted as illustrative and not in alimiting sense.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. An article of the character described comprising a seamless tubularbody portion made of material composed principally of transparentnitro-cellulose and a metallic band secured at the interior of an end ofthe body portion.

2. An article of the character described comprising a seamless tubularbody portion composed of flexible, non-metallic, tough and substantiallywaterproof transparent material, said portion having a closed end and ametallic band adhesively secured on the interior side to the 0 en endthereof, said band adapted to remova 1y engage with an attachment.

3. An article of the character described com rising a'seamless tubularbody portion having a closed end made of material composed principallyof nitro-cellulose andaband adhesively secured at the interior of theother end of the body portion, said band adapted to removably engagewith parts for closing said container.

4. An article of the character described I comprising a seamless tubularbody portion opening and a composed of flexible, tough and substantiallywaterproof material having only one end metallic band secured to theinner rim of said opening, said rim portion being transparent to allowsaid band to be visible thru said rim, said band adapted to engage acover.

5. A container having a seamless body portion of light, transparentflexible material and a metallic band held in the interior of the mouthof said container by adhesion of the material to the band.

In testimony whereof I aflix m signature. ANTHONY D NIELS.
